How can I create a VM image in Azure and share it to other subscriptions?

I need to create a VM image that can be used by other people to create VMs in their own subscriptions.

I've looked at the Azure documentation for VMs and images. I can find info on how to create images and about how to create VMs from an image. But I cannot find any reliable information on whether there's any way to make my VM available to other people with their own subscriptions. The official Microsoft Azure documentation doesn't ever say whether or not this can be done. Some unofficial sources seem to say that I need to put the image in a Container and make the Container public, and people can copy it to their own subscription.

Can anyone tell me whether my goal in the first paragraph is possible, and if so how do I do it?
